초록

Respiratory syncytial virus (RSV)는 전 세계적으로 영유아에게 질병 부담과 사회적 비용이 매우 높은 병원체이지만 그 백신 개발은 상당히 지연되고 있다. 현재로선 단기-지속형 단클론항체인 palivizumab이 유일한 예방법이다. 그러나 최근 RSV 감염의 병태생리학에 대한 이해, 유전학의 발전, 모체 예방접종의 성공적인 시행 등으로 RSV 예방을 위한 단일클론 항체 및 백신의 개발이 급속히 추진되고 있다. 현재 2개의 장기-지속형 단클론항체 제제(nirsevimab 및 clesrovimab)와 2개의 모체 RSV pre-F 백신이 임상 3상 시험을 진행 중이거나 막 완료하였으며, 지금까지의 결과는 효과와 안전성 측면에서 매우 긍정적이다. 가까운 장래에 장기-지속형 단클론항체와 모체 예방접종을 통해 고위험군은 물론이고 기저질환이 없는 신생아 및 영유아들을 RSV로부터 효과적으로 보호할 수 있을 것으로 기대한다. RSV 예방의 새로운 시대에 빠르고 적절히 대비하기 위해서는 이러한 새로운 전략들에 익숙해지고 국내 RSV에 대한 역학 자료들을 계속 수집해 나갈 필요가 있다.

Respiratory syncytial virus (RSV) is a pathogen with a high burden of disease and social cost among infants worldwide, but the development of a vaccine has been delayed. The recent understanding of the pathogenesis of RSV, progress in reverse genetics, and successful implementation of other maternal immunizations have prompted the recent rapid development of monoclonal antibodies (mAbs) and vaccines for RSV prevention. Phase 3 clinical trials for two next-generation mAbs (nirsevimab and clesrovimab) and two maternal RSV pre-F vaccines are currently underway or have been recently completed. Soon, we might be able to protect young infants through long-acting mAbs and/or maternal immunization. Additionally, the development of live-attenuated vaccine candidates that are capable of avoiding enhanced RSV disease is ongoing. We need to gain familiarity with these newly developed strategies and collect epidemiological data on domestic RSV to adequately prepare for a new era of RSV prevention.
